Thus the wavelength of a 100 MHz electromagnetic (radio) wave is about: 3Ã10 8 m/s divided by 10 8 Hz = 3 metres. The wavelength of visible light ranges from deep red, roughly 700 nm, to violet, roughly 400 nm (for other examples, see electromagnetic spectrum).
Mumble, Putting a modem to bridge mode just makes it dumb, it will let anything pass though, though when hits the Router it will then get routed to where needs be. The option is really up to yourself. Once advantage would be, only the Router will need to be setup accordingly, as the modem just passes internet traffic.
